Its ok, its fun if you know the german voice actors and the story is interesting enough. I'd say if you get it for a discount <10€ its worth it - if you already played all of Daedalics Games and Broken Sword, Runaway etc.
The game mechanic is definitly interesting, but thats it. The puzzles arent that hard and they repeat quite a lot, if you played the Demo you basically saw everything. Additionally ist extremly short, maybe 1,5-2 hours max. This game isnt bad, but theres nothing challenging oder compelling about this it other then its interesting mechanic. If you never played a puzzle game before, if might be an easy starting point but if you played any Point and Click Adventure before you probably will be disappointed like me.
